LOCKING DEVICE FOR SWIVEL TYPE LIPSTICK CONTAINERS HAVING REEDED CAPS Filed May 29, 1947 INVENTOR. Robert L .M Knight Patented Oct. 18, 1949 LOCKING DEVICE FOR SWIVEL TYPE LIP- STICK CONTAINERS CAPS HAVING REEDED Robert L. McKnight, Watertown, Conn., assignor to Scovill Manufacturing Company, Waterbury, Conn., a. corporation of Connecticut Application May 29, 1947, Serial No. 751,420

3 Claims. (Cl. 20656) This invention relates to lipstick containers and particularly to the so-called swivel type of lipstick container wherein one part is rotated relative to the other for elevating and retracting the carrier cup therewithin.

More particularly this invention relates to a lipstick container in which the cover cap is provided with flutes having the appearance of reeds extending substantially the full length of the cap, and wherein the container is designed to interlock with this specially constructed cap so as to prevent accidental movement of the carrier cup within the container once the cap is in assembled position.

Specifically this invention resides in the construction wherein the inside shell is provided with an intermediate enlarged portion between the inside shell body proper and the operating head, and which intermediate portion is provided with spaced nibs or projections positioned to align with the open fluted end of the carrier cup, and fitting within the interior fluted recess portions as a locking feature.

In the drawing:

Fig. 1 is a side elevational view of the lipstick container embodying the invention and showing fragmentary portions of the cap partially removed from the container.

Fig. 2 is a side elevational view of the lower end of the inside shell of the container showing the carrier cup in dotted outline.

Fig. 3 is a transverse sectional view taken along the line 33 of Fig. 2.

Fig. 4 is a side view of the lower portion of the lipstick container showing the cover in section and in assembled position, and

Fig. 5 is a perspective view of the fluted cover member, per se.

Dispensing containers such as generally known as swivel type lipstick containers are of a class well known in the art and a brief description of the same is considered sufficient without necessarily disclosing all of the detail parts that g into the construction of the device.

Referring now to the drawing in which like numerals designate like parts throughout the several views, the numeral I0 refers generally to a swivel type lipstick container of the cylindrical type. In its construction the container In consists essentially of an outer tubular casing I I that is adapted to fit over an inside shell I2 having a helical member not shown disposed therebetween. The usual form of carrier cup I3 is slidably fitted within the inside shell I2 and supports from the outside of the cup and operating in a longitudinal slot It in the shell I2 and also coacting with a helical groove provided in the helical. member mentioned above as is well known. The inside shell I2 is formed with an enlarged operating head II terminating and closing the lower end of said shell I2 and serving as a convenience in operating the container. The shell also is formed with an intermediate cylindrical neck portion I8 connecting the head II to the body of the shell I2 and of a diametrical size comparable to the diameter of the tubular casing II. Both the operating head I1 and the intermediate neck portion I8 are exposed below the open end of the tubular casing II as seen in Figs. 1 and 4.

The container I8 is adapted to be closed when not in use by an elongated cover cap I9 fitting over substantially the entire length of the container II). This cover cap I9 is formed with a series of adjacently spaced circumferential flutes 20 designed to simulate reeds and extending throughout substantially the entire axial length of said cover cap, and thus providing for a series of scalloped interior recesses or grooves 2| leading directly to and opening through the open end of said cap. 7

In order to frictionally maintain the cover cap I9 assembled upon the container, the tubular casing I I is provided adjacent its lower end with a biased elongated outwardly projecting friction nub 22. The nub 22 is preferably biased as shown in Figs. 1 and 4 so as not to line up with any one of the flutes 20 of the cover cap I9 when being assembled and is of a length to extend at least across two of the adjacent flutes of said cap. The nub 22 is also specifically formed so that its lower end as at 23 is the highest point of the nub and gradually decreases in height so as to merge on a common plane with the casing at the opposite end of the nub as at 24. This construction of the nub 22 is such as to eliminate any abrupt shoulder interfering with the assembly of the cap I9 regardless of the position that the flutes 2|] may be in when said cap is being frictionally forced over said nub 22.

In order to prevent the inside shell I2 from being rotated relative to the casing II, once the cover cap I9 is in assembled position, the intermediate neck portion I8 is provided with radial projecting nibs 25 that are so spaced as to properly align with the interior fluted recesses 2| of the cover cap I9 when the latter is being assembled over said neck portion I8. These nibs cona rivet l4 having an enlarged head I5 projecting sequently will fit within the recesses 2| and thus prevent the operating head I! of the inside shell l2 being rotated relative to said cap I9 and, therefore, preclude any danger of the carrier cup I3 being elevated within the container l due to any misuse or accidental turning of the parts of the container.

I claim:

1. In a dispensing cylindrical container of the swivel type having means for elevating and retracting a carrier cup therewithin and employing an elongated cover cap having, flutes extending throughout substantially its entire length and providing for a series of scalloped interior recesses opening through the open end of said cap, said container comprising a tubular outer casing and an inside shell, said inside shell provided with an enlarged operating head terminating its closed end and an intermediate neck portion exposed at the lower end of said casing, said tubular casing having a biased nub formed outwardly of its wall and located adjacent. the lower end thereof, the length of said nub being such that in its biased position it extends across at least two of the flutes of said cap, and one or more nibs projecting from the neck portion and adapted to engage in the interior recesses. of said cap, said nub serving to frictionally engage said cap to hold it against. axial displacement andv said nibs serving to hold it against rotation relative to. said container when said cap is in completely assembled position.

2. In a dispensing cylindrical container of the swivel type having means for elevating and retracting a carrier cup therewithin and employing an elongated cover cap having a series of longitudinal grooves provided on the interior surface of said cap with said grooves opening through the open end of said cap, said container compris- 4 ing a tubular outer casing and an inside shell, said inside shell provided with an enlarged operating head terminating its closed end and an intermediate neck portion exposed at the lower end of said casing, said tubular casing having a biased nub formed outwardly of its wall and located adjacent. the lower end thereof, the length of said nub being such that in its biased position it extends across at least two of the grooves of said cap, and one or more nibs projecting from the neck portion and adapted to engage in the interior grooves of said cap, said nub serving to frictionally engage said cap to hold it against axial displacement. and said nibs serving to hold it against rotation relative to said container when said cap is in completely assembled position.

3. In a lipstick container as defined by claim 2 wherein the biased nub is at its maximum height at. its' lower end and gradually recedes in height toward its upper end for the purpose of facilitating the guiding of the cover with the interior grooves thereover.
